Chicago, Illinois – Above-normal precipitation combined with near-normal temperatures may increase snow chances across northern Illinois from Jan. 3–9.
According to the NOAA Climate Prediction Center’s 8–14 Day Outlook, northern Illinois is favored to receive above-normal precipitation during the first full week of January. Temperatures are expected to remain near seasonal averages, a setup that supports snowfall potential across the region, particularly during overnight and early-morning hours.
The outlook reflects a 33–50% probability that precipitation totals exceed early-January averages. While the guidance does not identify specific storm systems, it points to a weather pattern favorable for multiple snow events rather than a single major winter storm.
Areas closer to Lake Michigan, including Chicago and the northern suburbs, may experience periods of lake-enhanced snowfall if wind patterns align. Interior portions of northern Illinois could also see accumulating snow, especially during colder nighttime periods. Brief mixed precipitation is possible at times, but snow remains the primary concern given the temperature outlook.
Travel impacts are possible along Interstate 90, Interstate 94, Interstate 88, Interstate 80, and major commuter rail and freight corridors. Snow-covered roads, reduced visibility, and transit delays could affect commuters, students, airport operations, and commercial drivers.
The Climate Prediction Center emphasizes that 8–14 day outlooks represent probability trends, not guaranteed outcomes. More detailed forecasts, including snowfall amounts and potential winter weather advisories, will be issued by the National Weather Service as individual systems develop.
Residents are encouraged to monitor updated forecasts, prepare vehicles for winter driving, and remain alert for possible winter weather advisories or warnings as early January approaches.
